1960 ts americano 200 battery questions.

[icyuod2]

i have to head to the store to pick up a 6 volt battery for my 1969 honda ct90.

while i was there i figured i'd pick up a battery for my new toy (1960 ts 200 americano)
the ct battery is a 6volt, 5.5ah. would the other be similar?
i've ordered a few books to do some heavy reading before i start into the project, but if i can figure out what i need ahead of time, it will save me a second trip clear across town.

thx guys and gals
